SPECIFICATION forming part of Letters Patent No. 339,532, dated April 6, 1886.

Application filed October 28, 1885. Serial No. 181,125. (No model.)

To aZZ whom it may concern.-

v Be it known that I, LUTHER C. GROWELL, a citizen of the United States, residing at Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improve ments in Sheet-Delivery Apparatus, fully described and represented in the followingspecificatiomand the accompanying drawings, forming a part of the same.

[ This invention relates to a delivery mechanism of that class which is adapted to operate upon a continuous web to sever the same into short lengths or sheets, fold said sheets to convenient dimensions for handling, and, if desired, deliver the folded product divided into lots containing any desired number.

It is the especial object of the invention to provide a mechanism of this character which shall be capacitated to deliver products of various sizes or volumes so as to meet the wants of those publishers who issue papers which vary in size with the different days of the week.

To this end the invention consists, principally, in a novel organization of mechanisms by which this result is effected in asimple and economical manner.

The invention also includes an organization of mechanisms by which the product may be delivered folded to different dimensions, or by 36 which, when desired, it may be delivered in a flat or unfolded condition.

The invention also includes various improvements in certain of the individual mechanisms of which the complete delivery mechanism is composed.

As a full understanding of the invention can be best imparted by a detailed description of the construction, organization, and operation of the mechanisms in which it is shown as embodied, in the present case such description will be first given, after which some of the modifications which may be made in the construction and organization without departing from the invention will be pointed out.

A delivering mechanism embodying the pres ent invention in its most complete and desirable form consists of a web-turning or turning and associating mechanism consisting of suitably arranged turning-bars; a primary folding 5o mechanism consisting of one or more longitudinal folders, to which the web or webs pass from the turning or turning and associating mechanism; a severing mechanism by which the web or webs are severed into sheets, and which is arranged to receive the web or webs either direct from the printing mechanism or from the primary folding mechanism; asecondary or final folding mechanism, which is also a sheet-associating mechanism, and which is arranged to impart a transverse fold to each sheet separately, or to associate the sheets in pairs and impart a transverse fold to the associated pairs, or to permit the sheets to pass without being either folded or associated; a piling mechanism which is arranged to receive the folded sheets from the final folding mechanism and pile them in proper shape for removal; asheet-collecting mechanism which is arranged to receive the sheets from the final folding mechanism and collect theminto lots containing any desired number, and a second piling mechanism which is arranged to receive the collected lots of sheets and pile them.

The organization thus briefly outlined will now be described in detail, reference being had to the accompanying drawings, in which Figure l is an elevation, partly in section, of a delivery mechanism embodying the present invention, showing also a diagrammatic view of an ordinary form of web-printing mechanism. Fig. 2 is a plan View of the delivery mechanism, showing particularly the web-turning or turning and associating mechanism. Fig. 3 is a sectional elevation of the same, taken upon the line at or of Figs. 1 and 2. Fig. 4 is an enlarged sectional elevation of the final folding mechanism, and also of the severing and sheet associating and collecting mechan isms and the sheet-piling mechanisms. Fi 5 is a side elevation, partly in section upon a like scale, of the mechanism for collecting a, number of sheets when it is desired to deliver the sheets in an unfolded condition or without the final fold. Fig. 6 is a sectional elevation, upon a still more enlarged scale, of the final folding mechanism and of the severing and sheet-associating mechanism. Figs. 7 and 8 are details showing the means for operating the sheet-holding pins and the strippers of the sheet-associating mechanism. Figs. 9 and 10 are enlarged crosssections of the cylinder forming the sheetcollecting mechanism for collecting'the sheets into lots when they are to be delivered in an unfolded condition or without the final fold. Fig. 11 is a view showing the means for operating the sheet-holding pins of the folding mechanism and the strippers of the collecting mechanism. Figs. 12 and 13 are views similar to Figs. 4 and 5, illustrating a modified constructiongvhich will be hereinafter explained. Fig. 14 is a cross-section of the severing, folding, and associating mechanisms,illustrating another modified construction,which will also be hereinafter explained.

Fig. 15 is a plan view of the same. Fig. 16 is a plan View of the delivery mechanism, showing a modified arrangement of the webturning or turning and associating mechanism. Fig. 17 is an elevation ofthesame. Fig. 18 is a view similar to Fig. 16, showing another modified arrangement of the same mechanism. Fig. 19 is an elevation of the same; and Figs. 20 and 21 illustrate details,whicl1 will be hereinafter referred to. Fig. 22 is apartial front elevation of the fly for delivering the sheets from the collecting mechanism, showing particularly the guides, which are located between the fingers of the fly.

In many of these figures the frame-work for supporting the various parts is partly or wholly omitted, in order to more clearly show the other parts.

Referring to said drawings, it is to be understood that the printing mechanism therein shown is of an ordinary form of web-perfecting mechanism, consisting, essentially, oftwo form-cylinders, 97, two impression-cylinders, 96 98, and suitable inking mechanisms, as 101. This mechanism, as herein shown, is capacitated to perfect a double-width webthat is to say, a web which is of sufficient width to receive two or more printed pages abreast or widthwise, so that, being properly printed, it can be split longitudinally to produce duplicate side-by-side small products, or after being split can have its longitudinal sections associated to form products of larger volume. The web A led from the roll passes around the usual leading-rolls, 99, and through the printing mechanism by which it is perfected, after which it passes to conductors, by which it is directed to the delivery mechanism.

It is to be remarked that the printing mechanism thus briefly described forms no part of the present invention, but has been illustrated simply for the purpose of aiding in a ready understanding of the delivery mechanism. The printing mechanism may therefore be of any approved form, and may, as will hereinafter appear, be capacitated to perfect either a single, double, or greater width web.

The conductors by which the web is directed from the printing mechanism to the delivery mechanism consist of three series of tapes, 50, 52, and 15, two series of stationary guides, 51 and 9, and a series of switches, 18. The series of tapes 50 pass around pulleys 53, thence upward around a roll, 54, and forward over a roll, 55, and above and in contact with the upper surfaces of the bars 10 12, forming the web turning and associating mechanism, and return around pulleys 56 57 58. The series of tapes 52 pass around a roll, 59, located beneath the roll 54, and thence upward with the tapes 50, and return around the roll 55. The series of tapes 1' are stretched around the the roll 55, and a roll, 24, forming one of the fold-1aying rolls of the primary folding mechanism. The guides 51 bridge the space betwe n the cylinder 96 and the roll 59 and coact with the tapes 50. The guides 9 extend from the bars 10 12 to a point near the roll 55, and also coact with the tapes 50. The switches 18 bridge the space between the roll 55 and the ends of the guides 9. The web A, after being perfected, as stated, and as it emerges from between the cylinders 95 96, has its leading end entered between the tapes 50 and guides 51. The tapes 50 then act to conduct the end of the web forward and enter it into the bite of the tapes 5O 52, by which tapes it.

is then carried upward to and over the roll 55, in passing which roll it is split longitudinally into two sections, a b, which in the subsequent operations will be termed webs, by a slitter, 49, which is arranged and operates in the usual manner. The webs a b are then conducted forward by the tapes 50 and the guides 9 to the bars 10 12, forming the web turning and associating mechanism. The conductors just described are not essential, but they perform a useful function in threading the machine and also in supporting the web in its passage to the delivery mechanism.

The web-turning or turning and associating mechanism consists, as already stated, of two turning-bars, 1O 12. These bars, as shown in Figs. 2 and 3, are arranged at right angles to each other and in such position that the apex formed at their point of intersection points toward the slitter 49, and is at the center of the web and coincides with the line of division between the two narrow webs a b. The bars 10 12 are supported at their apex or point of union and at their outer ends by brackets 6 8, resting upon the frame-work. The brackets 8 are connected together by a tie-bar, 11, that tions may be changed with respect to the 1on-v gitudinal folders forming the primary folding mechanism, the object being to permit the web A, and consequently the webs a b, to be varied in width, within certain limits, and yet cause the webs a b to be presented to the longitudinal folders in such position that they will be folded centrally. This feature, however, forms no part of the present invention, as it is claimed in my prior application for Letters Patent filed March 28, 1885, Serial No. 160,436.

The turning-bars 12 are provided with curved guides 19, which are supported in any suitable manner and operate to direct the leading ends of the webs around the bars in the manner shown and described in my application for Letters Patent iiled June 17, 1885, Serial No. 168,924. These guides are not herein claimed, however, as they are claimed in said application. The guides 19 are provided with extensions 28, which extend laterally from the bars and serve to support the webs as they are led from the bars to a pair of leadingrolls, 4 1 48, l cated at the opposite sides of the machine. From the rolls i1 48 the webs a b are ledinward around a pair of adjustable register rolls, 45 47, and thence outward, as best shown in Fig. 3, over a pair of rolls, 42 416, located at the bases of a pair of longitudinal folders, 20 21, which form the primary folding mechanism. These folders may be of any well'known form. shown, however, they are of substantially the construction shown, described, and claimed in my application for Letters Patent filed February 8, 1884, Serial No. 120,116, to which reference may be had for a detailed description thereof.

As shown in Figs. 1 to 3, the folders 20 21 are pivotally secured at their bases to bosses projecting from the framework through supporting'arms which are capable of oscillation on said bosses. with the shafts of the rolls -16 42, through which bosses said shafts pass and find bearings therein. By thus supporting the bases of the folders their surfaces are always presented in a true tangential line from said rolls 46 42 in any adjustment of their apexes by the rods 71. The longitudinal folders thus supported are arranged with respect to each other so that their bases at the rolls 46 42 are parallel while their apexes point outward in opposite directions, and are each provided with external turners formed by the pairs of rolls 22 and 23, and with the single pair of fold-laying rolls 24 25, all of which find suit able hearings in the frame-work.

It is to be observed that the rolls 24 25 lie parallel with the printingcylinders, and also that they co-operate with both of the folders 20 21, and also that they are of suificientlength to receive both of the webs a 12 side by side when they are in an unfolded condition. The purpose of this is to permit the webs, when desired, to be led directly from the roll 55 to thesevering and secondary folding mechanism, instead of passing to the primary folding mechanism, as will hereinafter more fully ap pear.

After leaving the rolls 24 2"),thewebs,eithcr unfolded or longitudinally folded,pass side by side into the control of a pair of cylinders, 31, which are of sufficient length to receive As herein These bosses are concentric the webs in an unfolded condition,aud which, together with theirauxiliary devices, form the severing and the folding and associating mechanisms,hefore referred to.

Referring now particularly to Figs. 4 to 8 and 11, the organization of these mechanisms will be described. The cylinder 30, which, as here shown, is of a circumference equal to the length of two sheets, is provided at opposite points with cut-ting grooves 4,and the cylinder 31, which of like size, is provided with ordinary severing-blades, 5,which are arranged to cooperate with the grooves 4 in the usual manner. The cylinder 30 is provided just in the rear of the grooves 4 with sets of impalingpins 3 3*, which are mounted upon arms extending from rock'shafts. 29, journaled in the cylinder and are arranged to be protruded and retracted through openingsin the cylinder in the usual manner. The pins are protruded by means of springs, (not shown,) and the shafts 29 are provided with arms 4.3, which, as the cylinder revolves, are engaged by a stationary cam, 77, (see Figs. 5 and 11,) so as to rock the shafts and cause the pins to be retracted to release the sheets atthe proper point. The cylinder 30 is also provided at the i proper points between the sets of pins with two ordinary rotating foldingblades, 2, which are operated by means of a cam, (not shown) in the usual manner, to fold the sheets oh the cylinder and into the bite of a pair of foldingrolls, 13 14:, from which rolls the sheets pass I to the piling mechanism. The partsjust described constitute the severing mechanism and the secondary folding ,mcchanism, before referred to.

The cylinder 31 is provided. just in the rear of one of the blades 5,with a set of impalingpins, 80, which are mounted upon arms extending from a rock-shaft, which is jonrnaled in the cylinder and is provided with an arm, 81, (see Figs. 7 and 8,) by which it can be rocked to and secured in position to keep the pins either protruded beyond 01 retracted within the cylinder, according as it is desired to associ' ate sheets or not. The pins are provided with corresponding stripper-fingers, 82, which are mounted upon a rock-shaft, 78, which is journaled in the cylinder, and is provided with an arm, 83, which, as the cylinder revolves, engages with a stationary cam, 86, (see Figs. 7 and 8,) and is thereby operated so as to rock the shaft 78 and cause the fingers 82 to strip the leading ends of the sheets from the pins 80 and direct them into a pathway by which they are represented to the cylinder 30 in position to be associated with the next following sheets, so that the two will be folded together 1 between the rolls 13 l-t, all as will be more fully. explained when the operation of the mechanism is described. The stripper-fingers 1 82 are held in their normal position close against the surface of the cylinder by means of a spring or springs, (not shown,) and the cam 86 is supported upon rods 7 9, which are i made adjustable in the framework by means of a screw, 93, so that when sheets are not to be associated the cam may be moved out of the path of the arm 83, and thus prevent the stripper'fingers from being operated.

The pathway into which the sheets are direeted by the fingers 82 is formed of two series of tapes, 84 88, and two series of guides, 91 92, as best shown in Figs. 4 and 6. The tapes 84 pass around pulleys 85 87, and run in close proximity to the lower side of the cylinder 31, while the tapes 88 pass around pulleys 89 at the side of the pulleys 87; thence under pulleys 87 and around pulleys 90, located in close proximity to the cylinder 30; thence for a short distance in contact with said cylinder, and thence around the roll 14 and back to the pulleys 89. The guides 92 bridge the space between the pulleys 85 and the cylinder 30,

and cooperate with the tapes 88, and the guides 91 bridge the space between the pulleys 89 and the cylinder 31, and co-operate with the tapes 84.

The parts just described form the sheet-associating mechanism, before referred to.

As the folded sheets emerge from the folding-rolls 13 14, they are projected between guides 94, and as they are released from the folding-rolls they pass into the control of two series of tapes, 15 16, by which they are conveyed to the piling mechanism, which co-opcrates with the final folding mechanism to pile the folded sheets. This piling mechanism, as herein shown, is of substantially the character as that shown and described in my former Letters Patent, No. 281,754, and consists of a rotating cylinder or carrier, 32, which is provided with sheet-grasping devices, which are arranged to grasp the leading ends of the sheets, carry them forward, and deposit them against stops 42 and upon a slowly-moving apron or series of belts, 41, which pass around rolls, as 38 39, and by which the sheets are conveyed away from the machine. The stops 42 will preferably be provided with mechanism such as shown and described in my application for Letters Patent filed Octoher 6, 1884, Serial No. 144,808, by which the folded sheets will be piled irregularly, so that they can be dividedinto lots containing some predetermined number without the necessity of counting.

The tapes 15 pass around pulleys 33, located a short distance below the roll 13, thence downward beneath pulleys 36, and upward around the carrier 32, returning around pulleys 34. The tapes 16 pass around pulleys 35, located by the side of the pulleys 33, thence downward around the pulleys 36, thence upward, running for a short distance in contact with the carrier 32, and returning around pulleys 37. It will be observed that the pulleys 33 35 are placed a short distance apart, so as to prevent the tapes 15 16 from coming into close biting contact until they arrive at the pulleys 36. This permits the folded sheets to be projected downward between the tapes for some distance before they actually come under the control of the tapes, thus preventing the sheets from wrinkling or buckling in passing from the control of the rolls 13 14 to the control of the tapes, when, as is usually the case, the latter and the carrier 32 are run at a reduced speed.

" The sheet-collecting mechanism, by which the sheets may be collected into lots to be delivered in an unfolded condition or with only the longitudinal fold, consists, essentially, of a cylinder, 60, which is arranged at the side of and a short distance from the cylinder 30, and is of the same length as the cylinders 30 31. As herein shown, this cylinder 60 is of a circumference equal to or slightly more than the length of one sheet.

Referring now particularly to Figs. 4, 5, 9, 10, and 11, the construction and organization of this collecting mechanism will be described. The cylinder 60 is provided around its circumference with a number of yielding pieces, a, which have the effect of enlarging the circun1- ference of the cylinder, as shown in Fig. 9, but also permit the cylinder to be gradually contracted in diameter as the sheets are acci1mu lated upon its surface, as shown in Fig. 10.

The yielding pieces 0, as shown in the present case, consist of curved spring-plates, which are secured at one end to the cylinder, and have their free ends bentinward and extended into openings in the cylinder. The ends of the pieces 0 which enter the openings in the cylinder are provided with projections, which engage with studs or pins 0, and thus limit the outward movement of the pieces 0, as best shown in Fig. 9. The construction and arrangement of the pieces 0 may be considerably varied without departing from the principle of the invention. For example, they might consist of spring-seated pieces extending lengthwise of the cylinder, or the cylinder might be made in sections, so as to be capable of expanding and then contracting as the sheets accumulate upon it. The cylinder 60 is also provided with aset of impaling-pins, d, which are mounted upon a shaft which is journaled in the cylinder, so as to have a slight rocking movement. The 'pins d are so positioned and project such a distance beyond the cylinder that when the cylinder is in operation the leading ends of the sheets, held by the pins 3 3 of the cylinder 30, will, as the latter pins are retracted, be impaled by the pins d and transferred from the cylinder 30 to the collecting-cylinder 60. The cylinder 60 is also provided with two series of cooperating stationary guides, e 1', which are supported upon suitable rods and are arranged to nearly surround the cylinder, and thus act to hold the sheets onto the surface of the cylinder, as shown in Fig. 10. The cylinder 60 is also provided with a series of stripping-fingers, n, which are mounted upon a rock-shaft journaled in the cylinder, and are arranged to normally lie within or upon the surface of the cylinder, and are provided with slots, through which the pins d project. The fingers n are IIS provided with means by which they are rocked outward at predetermined times, so as to strip the accumulated sheets from the pins (2 and guide their leading ends off the cylinder and into a pathway formed by the portions f of the guides e r. This operation of the strippingfingers is effected as follows: The shaft upon which the fingers are mounted is provided with an arm, m, having a stud or bowl which travels in the groove of a stationary cam, 63. (See Figs. 5 and 9.) The bowl of the arm in normally travels in a path concentric with the periphery of the cylinder 60; but the cam 63 is provided with a vibrating switch, 64, which is periodically operated, so as to cause the bowl to pass inward and travel along a surface, as 8, (see Figs. 11 and 20,) for a short distance, and thus rock the arm at and raise the fingers a, so as to strip the sheets off the pins d and direct' them between the guidesf, as shown in Fig. 10. The switch 64 is operated as follows:

i The switch is mounted upon a short shaft, t,

(see Figs. and 21,) which extends through the cam 63, and is provided with an arm, k, which is connected to an arm, 66, which is forked at its end and straddles a stud extending from the frame-work. (See Figs. 5, 20, and 21.) This stud carries a loosely-mounted gear, 67, in the face of which is formed a camgroove, 65, into which extends a stud project ing from the arm '66. The gear 67 engages with a gear, 68, (see dotted lines in Fig. 9,) which is mounted upon the shaft of the cylinder 60. The cam-groove 65 is so formed that the switch 64 will be rocked at each revolution of the gear 67, but the gears 67 68 are so proportioned that the bowl of the arm on will not be in position to be directed inward by the switch at the time the switch is rocked, except at the end of each tenth revolution, thereby allowing ten sheets to be accumulated upon the cylinder 60 between each two vibrations of the fingers n.

Although the means as just described for operating the stripping-fingers forms a practical arrangement for so doing, any other wellknown means may be employed, as well as different sized and proportioned gears, to cause the cylinder to accumulate a greater or less number of sheets.

As the accumulated sheets emerge from between the guides f, they pass in front of an ordinary fly, 61, by which they are piled upon a table, 62. This table may, and preferably will, be provided with the well-known means by which it is shifted at regular intervals, so as to produceirregularities in the pile ofsheets, and thus enable them to be separated into lots containing any desired number without the necessity of counting.

The fly 61 is operated by any of the wellknown means for that purpose, and there are preferably provided stationary guides, as 76, (see Figs. 4. and 22,) which lie between the fingers of the fly, and against which the sheets will rest as they pass downward in front of the fly. The sheets from the fly, instead of being deposited upon a table, as 62, may be deposited upon a slowly-moving apron or series of belts, and in such case the irregularity in the pile caused by the movement of the apron or belts will efiect the counting.

In order to prevent a lot of accumulated sheets from falling suddenly as soon as released from the cylinder 60, and thus becoming disarranged, there are provided a pair of slowlymoving segmental rolls, 69 70, between which the lot of sheets passes as it emerges from the guides f. These rolls are cut away for the greater portion of their circumference or made segmental, so as to permit the lot of sheets to pass freely between them until their full portions come together, when the rolls will nip the lot of sheets and feed it slowly downward in front of the fiy. The rolls 69 70 are geared together by gears 74 75, and are driven from the gear 72 through an intermediate, 73, which is of suitable size to properly time the 'rolls 69 70.

The various other moving parts of the mechanism herein described are provided with suitable engaging-gears, by which the several parts are properly timed with relation to each other.

The cylinder 60 and the fly 61, and also the carrier 32 and its tapes and the apron or belts 41, will be driven in such manner that they can be thrown out of operation when desired.

The gears for driving the various parts are not herein shown, because they can be readily supplied by any ordinarily skillful mechanic.

The remaining features of construction will be described in connection with the description of the operation of the mechanism.

The delivery mechanism, organized as here in shown and described, is capacitated to de liver the printed product in the following forms and conditions-viz: In the form of single full sheets, either in an unfolded condition or folded once longitudinally and once transversely, or once transversely; in the form of pairs of full sheets associated together and folded, as above; in the form of four full sheets, said sheets being first associated in pairs and folded longitudinally andthe pairs associated and folded transversely; in the form of a single full sheet and a single halfsheet associated together and folded once lougitudinally, or once longitudinally and once transversely; in the form of two full sheets and two half-sheets, the full and half sheets being first associated in pairs and folded longitudinally, and the pairs then associated and folded transversely; or in the form of halfsheets in an unfolded condition or folded once transversely.

To deliver single full sheets in an unfolded condition, the arm 81 will be shifted to the position shown by dotted lines in Fig. 7, so as to retract the pins 80, and the cam 86 will also preferably be moved outward, so as to not engage the arm 83, thus rendering the fingers 82 idle. The blades 2 and the carrier 32 will also be rendered idle, and the collecting-cylinder 60 and fly 61 will be thrown into operation, and the switches 18 will be turned and secured in the position shown by dotted linesinFig. 1. The web A will be split by the slitter 49, and the two sections or narrow webs a 1), instead of passing forward to the turning-bars 12, will pass downward along the tapes 2', as shown by dotted lines in Fig. 1, and be entered side by side between the rolls 24 25 and the cylinders 31, where their leading ends will be impaled by one set of the pins 3' or 3, and carried around upon the cylinder 30. As the cylinders 30 31 complete a half-revolution one of the blades 5, co-operating with the corresponding groove, 41, will sever the webs, and their freshlysevered ends will be impaled by the otherset of the pins 3 or 3. At or about the same time that this takes place the pins upon which the leading ends of the now severed sheets are impaled will be retracted by the cam 77, and at the same time the pins (1 of the cylinder 60 will impale the leading ends of the sheets and take them off the cylinder 30 and onto the cylinder 60. At the end of the next half-revolution of the cylinders 30 31 another pair of sheets will be severed from the webs a b, and these sheets will in like manner be taken by the pins d and carried onto the cylinder 60 on top of the sheets already there, and so the operation will continue to be repeated until the proper number of sheets has been accumulated upon the cylinder 60, when the fingers n will be operated, as already described, to strip the accumulated lot of sheets off the pins (1 and direct them to the fly 61, by which they will be piled upon the table 62.

To deliver single full sheets with one longitudinal fold, the adjustment of the mechanisms will be the same, except that the switches 18 will be turned down to the position shown in Fig. 1. The webs a b will then, instead of passing downward along the tapes 11, pass forward between the tapes and guides 9 to the turning-bars 1O 12, around which bars they will be directed by the guides 19, as shown in Fig. 2, after which they will pass around their respective rolls 48 4.7 46 and 44 4.5 12 to their respective longitudinal folders 2O 21, in pass ing which folders they will be folded longitudinally, as shown in Fig. 3. After leaving the folders 20 21, the now folded webs will pass between the rolls 24 25 and enter side by side between the cylinders 30 31, after which the operation is exactly the same as already described, except that the sheets, instead of being delivered in an unfolded condition, are folded once longitudinally.

To deliver single full sheets with onelongitudinal and one transverse fold, the foldingblades 2 of the cylinder 30 will be rendered operative, the cylinder and fly 61 will be thrown out of operation, and the carrier 32 will be thrown into operation. The webs a I) will be folded longitudinally, the same as just described,butthelongitudinally-folded sheets,

instead of being taken by the pins 01 of the cylinder 60, will, when released from the pins of the cylinder 30, be folded off the cylinder by the blades 2 into the bite of the rolls 13 14, from which rolls they will be carried by the tapes 15 16 to the carrier 32 and be piled upon the belts 41.

To deliver single full sheets folded once transversely, the adjustment of the mechanisms will remain the same as last described, except that the switches 18 will be turned up to the position shown by dotted lines in Fig. 1. The operation will be the same as last described, except that the webs a 12, instead of passing forward to the turning-bars 10 12, will pass downward along the tapes t to the rolls 24 25.

To deliver pairs of full sheets folded either once longitudinally or oncelongitudinally and once transversely, the adj ustments and operations will be respectively the same as in delivering a single sheet folded to the same dimensions, except that the web 1), instead of. passing from the roll 45 to the roll 712 and folder 21, will be led around an adjustable register-roll, 102, and thence over the roll 46 onto the folder 20, so as to be brought under and associated with the web a, as shown by dotted lines in Fig. 3.

To deliver pairs of full sheets associated and folded once transversely, the pins 3* will be retracted within the cylinder 30, and secured in that position, the pins will be protruded beyond the periphery of the cylinder 31, as shown in Figs. 6 and 7, the cam 86 will be moved inward, so as to operate the fingers 82, as shown in Fig. 8, and the switches 18 will be turned up to the position shown by dotted lines in Fig. 1. The webs c b, instead of passing forward to the turning-bars 1O 12, will pass downward along the tapes 2' and be entered between the cylinders 30 31, in position to be taken by the pins 80 and carried around upon the cylinder 31. Asthe leading ends of the webs arrive at a point above the pulleys 87, the fingers 82 will be operated by the cam 86, as shown in Fig. 6, so as to strip the ends of the webs from the pins and direct them into the pathway formed by the tapes 84 88 and guides 91 92. Vhen the cylinders 30 31 have completed one-half a revolution, the webs will be severed, and the freshlysevered ends will be taken by the pins 3 and carried forward upon the cylinder 30. The sheets which were directed off the cylinder 31 will in the meantime be carried forward by the tapes 84 88, and will have their leading ends presented to the cylinder 30 at the roll just in time to join with the leading ends of the webs held by the pins 3, so as to be taken by said pins, and thus become associated with the second pair of sheets severed from the webs. The pairs of sheets thus associated will at the proper time be released by the pins 3, and folded off the cylinder 30 by one of the blades 2. The pairs ofsheets thus associated and folded will then pass to the carrier 32, and be delivered the same as already described.

To deliver four full sheets associated and folded as hereinb'efore stated, the adjustment and operation will be the same as in delivering a two-sheet product folded to like dimensions,

except that the pins 3 will be made inoperative and the pins 80 and fingers 82 will be made operative.

To deliver one full and one half sheet associated and folded either once longitudinally or once longitudinally and once transversely, the adjustments and operations will be respectively the same as in delivering two full sheets folded to like dimensions, except that the web I) will be of only half-width.

To deliver two full and two half sheets associated and folded as hereinbet'ore stated, the adjustment and operation will be the same as in delivering four full sheets folded to the same dimensions, except that the web b will be of only half-width.

To deliver half sheets either in an unfolded condition or folded once transversely, the ad justments and operations will be respectively the same as in delivering single full sheets in the same conditions, except that the slitters 103 (sec dotted lines in Fig. 2) will be putinto operation, so that the webs a and b will he each split longitudinally.

In those cases where two sheets are asso ciated and then folded longitudinally, it will be desirable to have thesheets pasted together along the line of the longitu ilinal fold. This can readily be done by providing a pasting apparatus, as 101, (see Fig. 3,) by which a line of paste will be applied to the longitudinal fold-line of the web a as it passes the roll 47. In those cases where pasting is not required the pasting apparatus will be thrown outof operation.

If desired, the full sheets maybe split on the line of the longitudinal fold by means of slitt-ers, as 105, located as shown by dotted lines in 3, or in any other suitable position.

The mechanisms constructed and organized in the manner hcreinbefore described embody the invention in what I regard as the most complete and desirable form.

The arrangement or organization of the mechanisms, and also the construction of many of them, may be varied considerably without departing from some of the principal features of the invention.

The turning bars 10 12, forming the webturning or turning and associating mechanism, instead of being arranged as shown in Figs. 1, 2, and 3, may be reversed in position, as shown in Figs. 16 and. 17; or the bars, instead of being arranged at right angles to each other, may be arranged parallel to each other, as shown in Figs. 18 and 19; or the web-turning or turning and associating mechanism may be arranged in any other suitable manner to accomplish the necessary result. So, also, the folders 20 21, instead of being so arranged that their apexes point in opposite directions, may

be arranged to point in the same direction, as shown in Figs. 18 and 19.

One of the folders 20 or 21 may be omitted; but in such case a single instead of a double width web will be used when it is desired to deliver single full sheets folded longitudinally.

So, also, the whole mechanism, instead of being capacitated to operate upon a doublewidth web, may be only capacitated to open ate upon a singlewidth web. In such case of course two sheets could not be associated and folded longitudinally.

The secondary or transverse folding mechanism, or both this mechanism and the severing mechanism, instead of being parallel with, may be at right angles to, the printing-cylinders. In such cases the turning bar or bars 10 12 may be arranged to act upon the web or webs after it or they pass the longitudinal folder or folders; or the bar or bars may be arranged to turn the web or webs to present it or them to the severing and transverse folding mechanisms, instead of to the longitudinal folder or folders; or even when the transverse folding mechanism is parallel with the printing-cylinders the turning bar or bars may be arranged after instead of before the longitudinal folder or folders.

The transverse severing and folding mech anisms, and also the sheet-associating mechanism, may be of a different form from those shown without departing from the principal features of the invention. For example, these mechanisms may be organized as shown in Letters Patent No. 817,740, and as illustrated in Figs. 14 and 15. In this case the fingers S2 and the pathway formed by the tapes 84 88 and guides 91 92 are dispensed with, and the cylinder 31 is ofa circumference equal to the length of only one full sheet. and is as a consequence provided with only one blade 5, and the pins 80, instead of being held stationary either in their protruded or retracted position, are held in a protruded position by means of a spring, and are retract-ed to release the sheets by means of a cam, w. carried upon the cylinder 3(), and which engages with a stud upon the arm 87 in the same manner as in the Letters Patent referred to. When sheets are to be associated, the pins 3 will be rendered inoperative and the pins 80 operative. The first sheet will be taken by the pins 80 and carried around upon the cylinder 31, and at the end of the first revolution of the cylinder 31 the pins 80 will be retracted by the cam 10, so that the sheet on the cylinder 31 will be taken by the pins 3 and transferred to the cylinder 30, and thus become associated with the second sheet. \Vhen sheets are not to be associated, the pins 80 will be secured in their retracted position, and the pins 3 will be rendered operative.

The organization shown in Figs. 12 and 13 is substantiaily the same as that just described, except that an extra cylinder, 40, is provided to co-operate with the cylinder IIS to form the sheetsevering mechanism.

13,) by which the shaft will be rocked, so as to retract the pins and allow the sheet to be taken by the pins 80 and carried around upon the cylinder 31. The cam 26 is pivoted upon a stud, 71, in such manner that as the stud of the arm 43 passes the pivotal point of the cam it will bear upon the tail-piece 27 of the cam, and thereby rock the cam to the position shown by dotted lines in Fig. 11, so that as the pins 3 arrive at the cylinder 31 the stud of the arm 43 of their shaft will not be engaged by the cam, and these pins as a (301386. quence will notbe retracted. Asthe cylinder 31 completes its revolution, the pins 80 will be retracted by the cam 10, and the pins 3, not being retracted by the cam 26, will take the sheet from the cylinder 31 and associate it with the second sheet upon the cylinder 30. As the stud of the arm 43 of the shaft carrying the pins 3 passes the cam 26, it will engage the tail-piece 27 and rock the cam 26 back to its original position, so that it will operate to retract the pins 3 and allow the third sheet to be taken by the pins 80. When the sheets are not to be associated, the cam 26 will be moved outward by the stud 71, so as to be out of the path of the stud of the arm 43, as shown in Fig. 13, and the pins 80 will be secured in their retracted position.

It is to be remarked that the transverse severing mechanism, instead ofbeing wholly or partly carried by the cylinders 30 31, as shown, may be carried by an independent pair of cylinders, and in such case the severing mechanism may be arranged to sever the web or webs into sheets before it or they are longitudinally folded. In case this is done suitable tapes must of course be provided to convey the sheets to the transverse folding mechanism.

The forms of transverse folding and associating mechanisms shown are deemed sufficient to illustrate the principle of the invention; but other forms of mechanism may be employed for these purposes; or one or both of these mechanisms may be entirely omitted zttnd yet preserve certain features of theinvenion.

In regard to the collecting mechanism for collecting the-sheets into lots when they are to be delivered without being folded transversely, it is to be remarked that, although the form of mechanism for this purpose which is herein shown is regarded as, all things considered, the best for the purpose, any other form of mechanism may be used for this pur-- pose. and yet preserve the principle features of the present invention, and the same is to be remarked in regard to the sheet-piling mechanisms.

From the foregoing it will be seen that the 'present invention consists not so much in im' provements in the individual mechanisms of which the whole delivery mechanism is composed, as in the combinations or organizations of the several mechanisms, whereby they are capacitated to produce certain results.
